Question

6x2+x-2=0
помогите решить ?

Answer 1

D=1^2-4*6*(-2)=1+48=49; x1=(-1-7)/12, x2=(-1+7)/12. x1= -8/12= -2/3, x2=1/2. Ответ: x1= -2/3, x2=1/2.

Answer 2

6х²+х-2=0
D=b²-4ac=1²+4*6*2=49
√D=√49=7.
$x_1= frac{-b- sqrt{D}}{2a}= frac{-1-7}{12}= frac{-8}{12}= -frac23\ x_2= frac{-b+ sqrt{D}}{2a}= frac{-1+7}{12}= frac{6}{12}=0,5$
